Both examples show AI-generated drafts before editing. The interactive editor lets you rename, merge, add, or remove entries before export.
The AI reads your full document and understands meaning, not just keywords. For example, it distinguishes "bank" as a financial institution vs. a river bank based on surrounding context.
Each term is linked to the specific pages where it appears, with continuous discussions grouped into page ranges (e.g., 45-52) rather than individual page numbers.
The AI identifies related concepts and creates "see" and "see also" references to connect them — linking "machine learning" to "artificial intelligence" or "neural networks."
Everything the AI generates is a starting point. You have full control to rename terms, adjust hierarchy, merge duplicates, and add entries the AI may have missed.
Business, self-help, history, biography — extracts concepts, people, and themes with sub-entries.
Research concepts, methodologies, statistical terms, author references, and theoretical frameworks.
Procedures, equipment names, troubleshooting topics, and safety protocols with precise page references.
Ingredients, techniques, recipe names, and categorical groupings with cross-references.
